Patent number: 11161062Abstract: Filter systems disclosed herein collapse for storage purposes and include mechanisms to continuously fill an upper chamber, allowing it to be smaller and to include more filters. A UVC light in a lower chamber sanitizes water entering therein. Water entering the lower chamber may pass through a quartz tube near the UVC light for sufficient exposure. The UVC light may be cycled between shorter periods of higher intensity and longer periods of lower intensity. A low power source such as a small solar array and/or battery may power the UVC light. A proximity switch may control the UVC light by providing power to the light only when the upper chamber is engaged with the lower chamber which may protect the user from exposure to the UVC light. Sealing mechanisms between the upper and lower chambers, as well as tote mechanisms and an alternative bucket filter system are disclosed.Type: GrantFiled: March 12, 2020Date of Patent: November 2, 2021Assignee: WellspringPure, LLCInventors: Valdean Allen Johnson, Celia Roberts Johnson
